Title: LOW VOLTAGE BIAS OF NOZZLE SENSORS
Abstract:
Example implementations relate to low voltage bias of nozzle sensors. For example, a fluid ejection die according to the present disclosure may include a plurality of nozzles, and each nozzle may include a nozzle sensor and a fluid ejector, among other components. The fluid ejection die may also include a voltage reduction device to maintain a low voltage bias on the plurality of nozzle sensors during an operation of the plurality of nozzles. A plurality of sense circuits may be electrically coupled to a respective nozzle sensor among the plurality of nozzle sensors, and each sense circuit may evaluate a status of the respective nozzle after the operation.
